[Living conditions and gastroenteritis in the low income population of Tijuana, Mexico].

A cross-sectional study was carried out in the low income population of certain areas of the city of Tijuana, Mexico. Data collected showed that these suburban areas are inhabited by people from rural areas of Mexico, with minimum education, that basically work at the "maquiladoras". General hygienic conditions were poor and the services insufficient. The prevalence of diarrheas among the population was extremely high in the two weeks previous to the study, being highest for children less than one year old, in which the proportion with at least one episode of diarrhea was 47 per cent.

Serological evaluation of poliomyelitis oral and inactivated vaccines in an urban low-income population at Rio de Janeiro, Brazil.

Oral and inactivated poliomyelitis vaccines (OPV and IPV), were given to 160 children two months old, in a low income population at Rio de Janeiro. The vaccination was repeated 2 and 4 months later, always in association with diphtheria, tetanus and pertussis (DPT) vaccine. Blood specimens were collected before vaccination at the time of the third dose of vaccine and later at the time of measles vaccination, when the children were nine months old. The serological response to two doses of IPV showed high titres of antibody in all but one child and 100% conversion after three doses. Although poliomyelitis has been controlled in Brazil by the use of OPV in large mass campaigns, the results obtained with IPV support the possibility of its use in the basic immunization schedule, providing lower costs could be achieved for the inactivated vaccine.

Macrosomia: influence of maternal overweight among a low-income population.

Macrosomia (birth weight greater than 4000 gm) is associated with a wide variety of adverse intrapartum and perinatal outcomes. To evaluate the effect of pregravid obesity on infant birth weight, we examined data from a low-income population of women (n = 127,879). The population was divided into five groups on the basis of pregravid body mass index (weight/height) designated by the National Health and Nutrition Examination Survey II reference population (less than 25th percentile, 25th to less than 75th percentile, 75th to less than 85th percentile, 85th to less than 95th percentile, and greater than or equal to 95th percentile). The prevalence of infant macrosomia ranged from 5% for the lowest group to 17% for the highest group. With the use of the second group (25th to less than 75th percentile) as a reference, odds ratios (adjusted for maternal age, smoking status, race, height, parity, gestational age, and infant sex) for macrosomia for the five sequential weight groups were 0.6, 1.0, 1.3, 1.6 and 2.2. We conclude that pregravid overweight had a significant independent effect on birth weight outcome.

Nutrition education for cardiovascular disease prevention among low income populations--description and pilot evaluation of a physician-based model.

Low income Americans are at greatest risk for coronary heart disease but have least access to health promotion programs for life style modification. Primary care physicians may represent one of the few sources of preventive care available to the poor. However, the majority of physicians feel unprepared to help patients achieve dietary change, and few existing nutrition intervention programs address the special needs of low literacy populations. The Food for Heart Program was developed to facilitate dietary counseling experienced by primary care physicians who care for low literacy patients and to overcome barriers to behavior change faced by patients. The program consists of three components: (1) a validated dietary risk assessment that rapidly identifies atherogenic eating habits and requires no nutritional expertise to administer or interpret, (2) a structured diet treatment program that is culturally specific for a southern patient population and links practical behavior change recommendations with results of the diet assessment, and (3) a system for monitoring and reinforcement that prompts physicians to review progress, reinforce prior messages, and reward positive change. Behavior change theory is used to guide the intervention and readability of the material has been assessed at the 5-6th grade level. An evaluation study of the Food for Heart Program suggests that it has a positive impact on physician counseling and that patients are responding favorably to these efforts.

Correlates of breast-feeding in a low-income population of whites, blacks, and southeast Asians.

Infant feeding was examined in 492 children in a population-based survey conducted in a low-income, urban county of St Paul, Minn. Of 41 Southeast Asian infants who were foreign born, 93% (38) had been breast-fed compared with 10% (12) of Southeast Asian infants born in the United States (n = 116). Among non-Southeast Asian infants, 73% (173) of whites (n = 237), 63% (27) of blacks (n = 43) and 65% (36) of other ethnic groups (n = 55) had been breast-fed. Among the non-Southeast Asian infants, the initiation of breast-feeding was associated with higher parental education and with being married. Ethnic group, level of poverty, and participation in the Supplemental Food Program for Women, Infants, and Children during pregnancy did not appear to influence the initiation of breast-feeding. The findings indicate a higher incidence of breast-feeding than in previous surveys of low-income black and white women; however, this may reflect the higher educational level of the non-Southeast Asian study population. In contrast, the sharp decline in the incidence of breast-feeding among Southeast Asian infants who were born in the United States compared with those who were foreign born indicates the need for public health approaches to strengthen traditional breast-feeding practices.

Delivering Mental Health Services to an ambulatory, low-income population. Lincoln Community Health Center, Durham, North Carolina.

The social work and mental health unit of a comprehensive neighborhood health center delivers mental health services in coordination with general health services to ambulatory patients in a predominantly low-income black community. The unit works with other general health, mental health, and social service resources to provide a broad continuum of coordinated care. Services are provided to individuals, families, and groups, along with consultation, education, training, and referral. Before the unit was established in July 1971, the patients it serves were seen only for crisis intervention and in emergency rooms and did not have the benefit of a thorough evaluation or follow-up. Staff of the unit now identify potential medical and emotional problems before they reach the crisis stage, and they maintain contact with the patients to ensure that the prescribed regimen is carried out.

Effects of age on length of hospital stay in a low-income population.

A major focus of efforts to monitor and control health care expenditures has centered on factors related to hospital length of stay. Age, in particular, is usually assumed to be an important correlate of hospital length of stay, especially when diagnosis and hospital variables are also taken into account. In an analysis of data representative of Medicaid cases in 23 large New York City hospitals during 1972, these effects turn out to be less clear-cut than generally assumed. Although the first-order coefficients of length of stay regressed on age and the rank order correlation of the means are statistically significant, such wide differences in length of stay within age groups remain as to reduce the substantive impact of the observed findings. This same pattern of wide variations within age groups persists even when diagnosis is controlled by use of up to 80 covariant groups. In over half the 80 diagnostic categories, no significant age effects was found. When the age analysis is repeated using 23 hospitals as the covariants, estimated age effects differed between institutions, and a similar pattern of large within-group variation was observed. These findings are interpreted as a caveat to health care researchers who might otherwise plan overly sophisticated utilization review systems.

[The control of solid waste with the participation of a low-income population].

Two studies were undertaken with a view to improving the health conditions of a shanty town area in the city of S. Paulo, Brazil. The objective was to modify littering behavior and to implement litter-control procedures with the participation of the inhabitants. Results demonstrated the adequacy of the procedures adopted and suggest a possible contribution on the part of psychology to public health.

Epidemiological, dietary, toxicological and clinical nutrition studies on low-income population groups from a geographical area with endemic chronic arsenic poisoning.

An epidemiological, dietary, toxicological and clinical nutrition study, in an area with endemic chronic arsenic poisoning, was made. In a pilot study on 100 subjects from Antofagasta Commune, water dietary intake was associated with age (r = 0.678; P less than 0.000005). In a dietary survey (N = 220), performed to measure the mean and median arsenic doses, by age groups, there was a significant correlation amongst males (r = 0.800; P = 0.00956) and females (r = -0.791; P = 0.01121). A nutritional assessment of a male population sample (N = 100), of labourers and their children, showed a negative per cent change for food energy in 9 of the 10 age groups, with a maximum negative value of -47.4 (11--12 year-old group), when compared with U.S. recommended daily dietary allowances. For total protein intake, all age groups exhibited a negative per cent change, reaching a maximum value of -27.8 (7--10 year-old group). Since two boys with chronic arsenical dermatosis and prekwashiorkor were drinking water with a mean arsenic concentration of 0.08 and 0.06 ppm, respectively, a maximum permissible concentration of arsenic in drinking water of 0.01 ppm has been recommended as an international safety standard.

The planning of pregnancy among low-income women in central Harlem.

A planned pregnancy is considered desirable, in part because of the potential of a better pregnancy outcome. Since the improvement of pregnancy outcome is of particular relevance in low-income populations, we have compared the characteristics of women with planned and unplanned pregnancies in central Harlem with regard to those factors that might affect pregnancy planning such as sociodemographic factors, attitudes toward child-rearing, environmental stress, social support, and maternal mental health. Of the 416 women in the study, a minority (27%) reported their pregnancy as being planned. They differed from the remainder in being more likely to be married and/or living with a boyfriend or husband and to have been born outside New York City. The two groups did not differ in any other risk factor or in outcome in terms of birth weight and gestational age. The results provide little support for the lack of planning of pregnancy as an indicator of risk in a low-income population and suggest that improvement of perinatal outcome must involve more broadly based interventions that are not confined to the periconceptional period.

Breast-feeding among women attending women, infants, and children clinics in Georgia, 1987.

Breast-feeding is an important determinant of the health and nutritional status of children, particularly in lower socioeconomic populations. A major goal of the Georgia Special Supplemental Food Program for Women, Infants, and Children (WIC) is to increase the practice of breast-feeding among the women it serves. Breast-feeding practices were determined among a random sample of 404 women from a cohort of 2010 who attended WIC prenatal clinics in Georgia in 1986 and were expected to deliver in February 1987. Respondents were interviewed 6 months postpartum. Of these women, 24% initially breast-fed, but only 6% continued for 6 months or longer. The initiation of breast-feeding was associated with greater maternal education and with being married. The adjusted odds of breast-feeding for mothers who were married or living as married were 3.0 (95% confidence interval, 1.7 to 5.3) times greater than for mothers who were not married or living as married. Mothers with more than 12 years, 12 years, or 10 to 11 years of education were 5.2 (1.8 to 15.3), 2.7 (1.0 to 6.9), and 2.5 (0.9 to 6.9) times more likely, respectively, to breast-feed than mothers with 9 or fewer years of education. After adjustment was made for marital status and education, the remaining variables (ethnicity, parity, age, and employment status) did not influence the initiation of breast-feeding in this low-income population. The need for vigorous promotion of breast-feeding by the Georgia WIC program is emphasized by the low rate of initiation and short duration of breast-feeding in this low-income population.
